"Displacement"

📏Distance📏

The "length" of the path covered by a moving object in a given time is called the "distance" traveled by that object.


Definition of distance and its measuring formula


 "Distance" = Speed ×  Time  


Formula for calculating Distance, Speed, and Time


Displacement

The difference between the final and initial "positions" of an object is called its "displacement".

🏎💨SPEED🏎💨

 The "distance" traveled by an object in unit time is called the "speed" of the object.


A real example of the movement covered by an athlete.

"Speed" = Distance / Time


The mathematical formula for speed: distance/time


In the S.I. system, the unit of "speed" is meter per second (m/s).


💨Velocity💨

 The "displacement" of an object in unit time is called its "velocity".

   "Velocity" =  Displacement /  Time Interval 

The formula for velocity as displacement divided by time.


In the S.I. system, the unit of "velocity" is meter per second.


🌪Acceleration🌪

The rate of change of "velocity" of an object is called "acceleration".


Formula for acceleration: Final velocity - Initial velocity / Time


 "Acceleration" = Change in "Velocity" / "Time Interval"
